Never unless it's relevant to the setting.
I hesitate to say yes or no because ghosting comes in many levels. There are many people I prioritize last if at all, and there are some people that some would say I definitely have good reasons to ghost absolutely, but the potential for circumstantial nuance (especially in my life) would make this practically difficult to foresee myself doing. The closest I come to a perfect example of a ghosted individual is my best friend's birth mother who wants to steer his life away from mine and my other best friend's since she (the birth mother) is culturally discriminatory.
"Oh rabbits" sounds like something Wallace and Gromit would say.
"I'd challenge you to a battle of wits, but I see you're unarmed."
~ William Shakespeare, The Taming of the Shrew
"You want my children? Take them! I have the instrument to make more."
~ Caterina Sforza when blackmailed by kidnappers using her children as leverage (main source: Niccolo Machiavelli)
"We fulfill the demands of nature in a much better way than do you Roman women; for we consort openly with the best men, whereas you let yourselves be debauched in secret by the vilest."
~ Earliest recorded words of a Scot, third century AD (never change, Scotland).
Your emotions, on their own, are your own and natural to you. If anything should be judged, it's how someone goes about their life.
City life is built around noise/hustle. There is a reason coffee is a stereotype in New York City. This routine is emphasized over the needed eight hours of sleep.
Water quality via plumbing and even rain quality is generally lesser in cities. Rain is often affected by air pollutants that come from buildings and vehicles which mix with cloud matter, while plumbing quality is affected by the quality of pipes and aquatic infrastructure which is typically further from the source.
Walking is affected because you're living your life in an urban jungle with varying levels of danger (depending on the city) where your main range is measured in blocks rather than the openness of the world around you.
Have people in this industrial-loving place thought the advice was simply some kind of jab and chose to think rashly about it?
The three best things for you are water (drinking/hygiene), walks, and sleep. Ironically all things you get less of in a city.
You say that as if dictators, by their nature, aren't going to sneak up on us. The question, sadly, should be what we would do once one reveals themselves, and the answer to that is in a battle of wit VS law.
